Java

Java is a programming language developed by Sun Microsystems which offers developers the ability to write platform independent programs. One of the biggest advantages to the platform independent approach to programming is that programs can run as applets in a client's browser, rather than having to run on the server.

Java1 is available as a default program on your E&C and can be found in the /usr/local/bin directory on your server.

Installing Java2

Due to the nature of the Java2 license, there are several steps that you must go through in order to install Java on your E&C.

1. Dowload the J2SDK version 1.3.1 from http://www.sun.com/software/java2/download.html. You will be required to register with Sun before downloading the J2SDK. Once you have downloaded the file, save it on your E&C in the /var/distfiles/ directory (you may need to make the directory first).

2. Download the Linux JDK from http://java.sun.com/webapps/download/Display?BundleID=7163 and copy it into the /var/distfiles/ directory of your E&C

3. Download the BSD patch for the JSDK from http://www.eyesbeyond.com/freebsddom/java/jdk13.html and install it in the /var/distfiles/ directory of your E&C.

4. Once both the files have been placed in the /var/distfiles directory, install java by running the following commands as root from your E&C shell prompt.

   # cd /ports/java/jdk13

   # make

   It will take several minutes for make to build and install Java and all the dependencies.

In order for your Java programs to find the Java compiler, you will need to indicate the full path to java in the program, or add the path to your shell's PATH.
